This application note’s primary goal is to provide an easy-to-understand primer for users who are not familiar with 4-20mA current-loops and their applications. Some of the many topics discussed ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...

Significant efficiency and performance improvements can be realized by improving the current loop’s power supplies, replacing linear regulators with high-efficiency buck regulators. It also increases ...

Current sources are widely used in industrial control systems to transport analog process signals over long distances, but they are less widely used than voltage sources. This post loosely reviews the ...
